When near-eutectic Sn-Ag-Cu (SAC) alloys are used to make soldered ball-grid-array (BGA) assemblies, the grain size of the joints is very large. During thermomechanical cycling, the solder joint fatigue process is often initiated with recrystallizati

The deformation properties of near-eutectic Sn-Ag-Cu alloy were measured in temperatures ranging from −25 to 125°C, and down to strain rates of about 10×10−9. Results have been combined into a stress versus strain rate master curve. The measure

During the solidification of solder joints composed of near-eutectic Sn–Ag–Cu alloys, the Sn phase grows rapidly with a dendritic growth morphology, characterized by copious branching. Notwithstanding the complicated Sn growth topology, the Sn ph

Near-ternary eutectic Sn–Ag–Cu alloys are leading candidates for Pb-free solders. These alloys have three solid phases: β–Sn, Ag3Sn, and Cu6Sn5. Starting from the fully liquid state in solidifying near-eutectic Sn–Ag–Cu alloys, the equilib
